Column-to-column isolation in fed display

An electron emitter, comprising:

• a substrate;
• a first layer of conductive material deposited on said substrate;
• said first layer of conductive material patterned in stripes, with gaps between adjacent stripes;
• a layer of resistive material of a first vertical thickness deposited on said substrate;
• said layer of resistive material patterned with voids configured so that resistive layer material is absent from a major portion of said gaps;
• a layer of insulating material of a second vertical thickness deposited on said substrate over said patterned first layer of conductive material and layer of resistive material;
• at least one of said resistive material and insulating material layers shaped to continue the combined first and second vertical thicknesses of said resistive material and insulating material layers in continuous paths across said voids, bridging terrain discontinuities at said voids;
• a second layer of conductive material deposited on said substrate over said layer of insulating material and said continuous paths;
• said second layer of conductive material formed with a plurality of apertures over said stripes;
• said apertures extending through said insulating layer;
• and
• a conductive microtip formed in each aperture in electrical communication with said resistive layer.
